This invention relates to improvements in wire working pliers, and isdirected more particularly to pliers for removing or strip ping the,insulating covering from; wires, cables, or the like. 1

The principal obj ect of the invention is tion cutting blades andinsulation stripping grippers are arranged so that the insulation V isgripped for removal at the time'it is be ing .cut, as distinguished frompliers of the prior art wherein the cable is removed from a set ofcutting members and then inserted in other stripping members. 1'

With the above objects in View, I am able to produce. pliers that areeflicient in oper ation and simple in construction and which aretherefore economical to manufacture;

Other objects and advantages -'will" appear from the followingdescription of the invention which is illustrated in the form at presentpreferred by means of thevaccompanying drawings, in which:

Fig. 1 is a front elevational view of a pair of pliers embodying myinvention; and

Fig. 2 is'a rear side elevational view of the jaws of the pliers shownin Fig. 1.

Referring to the drawings in detail, 1 and 2 designate plier handles ofusual form that are pivotally connected at 3 in the well-known mannerhaving jaws 4 and 5 carried at the upper ends thereof. Plates or blades6 and 7 are secured to the jaws 4: and 5 respectively by rivets or thelike and are preferably arranged for a shearing action as the handlesaremoved or pressed together. Notches 8 and 9 are provided on the inneredges of the plates that are sharpened as indicated and adapted forcutting through the insulation of a cable .or wire.

The upper notch 8 in each jaw is shown in the form of a V'while thenotch 9 is semis circular, but it will be obvious that they may be ofany form desired depending upon the use for which the pliers are to beemployed.

, The sides of the plates below the notch 9 are preferably disposed atan angle relative to one another and are provided with a repeater filedJuly-3,

i In operation, the, adjusting screw is adusted soxthatth'ejaws andconsequently the cutting'blades'are prevented from outtlng throughtheiwire of a cable while of course allowing the cutters to cut throughthe covering. A covered wire or cable is inserted between the jaws andbetween the gripping members thereofand the handles pressed tobladesenter and cut through the'covering' while at the same time the coveringis clamped between the grippers to prevent a relative movement of thecovering with respect to the jaws.- hen the handles have sov I nether.By this action, the notchesof the been moved to their closed position,the pliers are rotated silghtly with respect to the cable so that thecovering, being gripped by the jaws, is twisted or turned with respectto the wire. This turning action loosens the covering from the wire andinsures a clean continuous out about the whole circumference ofthecable. Finally, the cable is pulled away from the pliers and the portionof the covering behind thebladesand embraced by the grippers will bestripped from the wire. A notch c in a side of one of the jaws isprovided and is adapted to scrape and cleanf 110 the end of the wirewhen the wire is drawn therethrough.

I am aware that many changes may be made in the form of the inventionwithout 1 departing from the scope thereof. I there.- iore prefer to" belimited by the "appended clainislrather than by the foregoing descrip-ition." V
